Prayers to the Holy Spirit and Trinity
Pentecost and Trinity, Folio 155r

At upper left, the Holy Spirit in the form of a dove descends in golden rays to the Virgin and gathered apostles below. The arched top of the quarter-page illumination parallels the painted architecture and vaulted ceiling above the scene. The Trinity is represented as three bust-length, haloed men of three ages, with the elderly crowned God the Father embracing Christ and the Holy Spirit, here represented as a young man. The group floats in a blue sky.
